9831ad3ce6 libc: speed-up flockfile()/funlockfile()
For Honeycomb, we added proper file thread-safety for
all FILE* operations. However, we did implement that by
using an out-of-band hash table to map FILE* pointers
to phtread_mutex_t mutexes, because we couldn't change
the size of 'struct _sFILE' without breaking the ABI.

It turns out that our BSD-derived code already has
some support code to extend FILE* objects, so use it
instead. See libc/stdio/fileext.h

This patch gets rid of the hash table, and put the
mutex directly into the sFILE extension.

b4867734b0 stdio: make internal symbols static/hidden
Although header libc/stdio/local.h declares the macros and private
variables of stdio, there are several internal symbols exposed
unexpectedly.

051ea9bc07 stdio: simplify __fremovelock()
... by removing extraneous NULL check, as free() already does it.
